Species Papilio aegeus, is known as the Orchard Swallowtail Butterfly or Large Citrus Butterfly. Observations (in Atlas of Living Australia) have their main distribution areas as the east coast regions of Australia, with a couple of sightings in the south-west of Western Australia, Central Australia and the Top End of Australia.
The larvae of this species are considered a pest, as they feed on citrus leaves.
Pictured here is the female Papilio aegeus aegeus. The female of the species have a series of blue and red crescent-shaped markings on their hind wings, whilst the same area on the hind wings of the male are black with cream-white patch and a single red spot on the hind wings.

Following is one of the caterpillar stages of the Orchard Butterfly.

If disturbed, the Orchard Butterfly caterpillars will rear up at the front, and briefly evert a red-orange forked “tentacle” (known as the osmeterium) from behind the head. This eversion is often very brief, and at the same time, the caterpillars will also emit a foul smell to deter predators (the emission is said to have a citrus smell).
The defence mechanism is called osmeterium. I had to poke its face with my finger to do this but it was partially retracted by the time I got the camera ready.
